Question

用java怎样实现批量打印

Answer 1

下面是实现Java批量打印功能的具体工具类，其中的Info类和UserClass为具体的快递面单中要打印的信息，以参数的方式传递过来，循环调用Java PrinterJob服务进行打印；这里的快递尺寸已经调整好，可以使用，如需添加只要根据实际的面单进行调整，也可以专门写一个接口类的形式来创建快递面单的尺寸，本人没有尝试；如遇问题欢迎留言，共同探讨！

Answer 2

创建个打印服务 异步调用 可以用webservice ，jms 等
最好可以限制打印张数 一次 ，看你业务上的需求

Answer 3

用循环 for, while都可以

Answer 4

据我说知，我打就是用java开发的。

Answer 5

问题具体些，打印什么？是输出还是什么
